J Be it known thatQI, BENJAMIN G. MILLS,

State of'-Massz lchusetts, have invented anew and Improved?SplitWheel,of which the following'is a specification: s

' My invention.consistsof the'twoparts of a flanges on the side of onepart-fitQupon'and are bolted-to the sidelof the other part,;so as toallow ,of applying-toand removing from the shaft such wheels in. lessspace than, is re-. quired when theyarefastened'by boltingtwo flangestogether at the sides of thewheel, and, it also allows of one part ofthe wheel being dovetailed in the other,-tosnstain the expanding actionof the key better than in the coin Figure 1 is apside elevation of myimproved split wheel. .Fig. 2is a section takenon line as w of Fig. 1.Fig. 3 is a sideelevation show? ing the two parts separated.

Similar letters of reference indicatecorresponding parts. i

Ais one parto'f the wheel, and B the other. The latter has curved;flanges G projecting side of part A, so as to be secured thereto bybolts D, when the two parts are fitted together on the shaft. I

In this example the partA comprises nearly I the whole of the wheel,being only asmuch less as is necessary for the notch E to admit theshaft to the center F, and said notch is made in dovetail shape, so thatthe part B will be securely held against the expanding effect of thekey, by which the wheel is secured to the shaft; but I do not limitmyself the wheel will have to be located as far from another wheel orother object on that side from which the part B enters as the thicknessof the wheel at the hub. I Having thus described my invention, I claimas new and desire to secure by Letters Paten t-- 1. A split wheelcomposed of two part-s, A
